How to send multiple variables in one single sender? - swift

Question

I'm trying to send multiple variables in one single sender to show it in the Viewcontroller that it's connected to a segue named menuENG. I have five buttons and each button should send different information because is a dictionary and each button is a word. But I want to do this thru one sender. I tried the following code to make it but it is not working.
p.s.: I tried making an array but Xcode goes crazy.
#IBAction func abstractionENG(sender:UIButton) {
return perfomanceWithIdentifier("menuENG",sender:nil)
}

Answer 1

I think you can send the dictionary and there is something wrong with this line return perfomanceWithIdentifier("menuENG",sender:nil)
Anyway you can seperatly identify which button is clicked by tag and create dictionary on base of clicked button now you can send the complete dictionary to the sender.
#IBAction func abstractionENG(sender:UIButton) {
var dictSendData:[String:Any] = [:]
if sender == btn1
{
dictSendData.updateValue("abc", forKey: "key1")
dictSendData.updateValue("pqr", forKey: "key2")
}
else if sender == btn2
{
dictSendData.updateValue("xyz", forKey: "key1")
dictSendData.updateValue("123", forKey: "key2")
}
else
{
dictSendData.updateValue("123", forKey: "key1")
dictSendData.updateValue("abc", forKey: "key2")
}
self.performSegue(withIdentifier:"menuENG", sender: dictSendData)
}

1- assign segue action to IBAction function - assign tag id to ever button
you have already implemented it .
2- your IBAction function should run another function to run performSegue function
example :
self.performSegue(withIdentifier: "openAnotherViewController",sender: sender)
3- go to destination view Controller and create reciver variables "Maybe you can use optionals " .
var receiverInt :Int = 0
var receiverInt2 :Int = 0
3- go to the source view Controller and pass variables
// MARK: - Navigation
// In a storyboard-based application, you will often want to do a little preparation before navigation
override func prepare(for segue: UIStoryboardSegue, sender: Any?) {
// Get the new view controller using segue.destinationViewController.
// Pass the selected variable/object to the new view controller .
if segue.identifier == "openAnotherViewController" {
let destinationController = segue.destination as! OtherViewControllerClass Name
// identify button by tag number
if (sender as! UIButton).tag == 200 {
destinationController.receiverInt = self.sourceInt
}else{
destinationController.receiverInt2 = self.sourceInt2}
}
}

Thank you everyone for the help fixed the issue by this way >

override func prepareForSegue(segue: UIStoryboardSegue, sender: AnyObject?) {
if(segue.identifier == "menuENG") || (segue.identifier == "menuESP"){
if let destinationViewController = segue.destinationViewController as? DefinitionViewController{
if let data = sender as? Array<String>{
destinationViewController.tittle = data[0]
destinationViewController.def = data[1]
destinationViewController.link = data[2]
}
}
}
}
PS: note this code is connected to the DefinitionViewController ( Controller of the view) and to a model. ( project was made by M.V.C way).
Again Thx everyone for your help. hope the code help other people in the future.
